Dandelion, I have not seen anyone recommend my favorite yet, so thought I would chime in. It is a Toshiba TIMM 20" multimedia monitor that has a TV tuner, RGB input and Video input. It will only display a maximum resolution of 800 x 600, but since you said you wanted a 15kHz display for AGA that resolution should be okay. I am pretty sure it will display 30 or 31 kHz VGA signals too. They are hard to find, but I am lucky to have two of them. Great for Video Toaster setups. It is a beast size wise, but I think well worth it.
